Reglyph

Reglyph is a simple tool which parses an OpenType or TrueType font and outputs its Unicode coverage (i.e. the list of its supported glyphs). The output can be formatted in a ready to use regular expression.

Reglyph can be used:

• when needing to find missing glyphs in Adobe InDesign or any other rich-text editor that provides a regex-compatible search & replace function,
• for extending the supported range of a web page with the unicode-range property of @font-face in CSS3,
• in any other situation where you need to know which Unicode characters are supported by a font.

Usage

Reglyph can be used in a terminal or as a Node.js module.

Command-line tool

First you will need Node.js to be installed on your computer.

Then run the following command to install Reglyph:

$ npm install -g reglyph

To use Reglyph against a font file, simply type in a terminal:

$ reglyph path/to/font --option value

Avalaible options are:

• -p or --preset is the preset to use to format the output. If not specified, the default preset "perl-negate" is used.
• -c or --custom-presets is the path to a custom preset file for overriding the default one. Note that the new JSON object is merged with the old one, so built-in presets will remains available until you override them.
• -l or --list-presets outputs the list of available presets with their descriptions. Can be used in combination with the -c option.
• -V or --version outputs Reglyph current version.
• -h or --help shows Reglyph help for CLI.

Node.js module

Reglyph can also be used as a Node.js module with require("reglyph"). Please read the source for more information about this.

Examples

The command $ reglyph path/to/font/Dashley.ttf outputs a regular expression which can be directly used in Adobe InDesign (GREP search) for finding glyphs not supported by the Dashley font:

[^\x{0020}-\x{005A}\x{005C}\x{0061}-\x{007A}\x{2013}-\x{2014}\x{2018}-\x{2019}\x{201C}-\x{201D}\x{2022}]+

The command $ reglyph path/to/font/Dashley.ttf -p html outputs the enumeration of supported hexadecimal html entities:

  ! " # $ % & ' ( ) * + , - . / 0 1 2 3 etc.
